| 2 | A Case Study: Data Transparency of Clinical Trial Data | Sherry Meeh | Data Transparency (DT) of clinical trial data is in high demand in today's world of increasing research needs and new regulations across the globe, including US Food and Drug Administration Amendments Act of 2007(FDAAA) regulations of protocol/result disclosure in clinicaltrials.gov; US California Consumer Privacy Act (CCPA); EU Clinical Trials Regulation 536/2014(CTR) / EudraCT requirements; European Medicine Agent Policy on Publication of Clinical Data for Medicinal Products for Human Use (or, EMA Policy 0070); EU General Data Protection Regulation (GDPR); Health Canada's Public Release of Clinical Information (PRCI); and Japan Pharmaceutical Manufacturers Association (JPMA) Information on Japanese Regulatory Affairs. Recently, in 2019, the FDA has concluded the Clinical Data Summary Pilot Program and is proposing a new integrated review template. Therefore, a holistic DT process is needed to face the challenge of the complexity of different regulations and data utility needs | clinical trial, clinical data, trial summary, phase i, data protection, threshold | source presentation source |

| 3 | A Collaborative Approach to Analysis Standards | Margaret Merlino, Marleen Nijs |
When is a standard not a standard? When no one uses it! While that may be a bit exaggerated, to mitigate this possibility Janssen has developed a collaborative model for not only creating new analysis standards for the Janssen study teams but also for correcting and enhancing them. The standards include templates for select study documents, analysis dataset metadata and template code, and code to produce tables, listings and graphs. These are aligned with CDISC standards. The ongoing effort to keep these standards relevant and useable by our study teams involves the teamwork from representatives from three areas: the analysis standards team, statistical programming, and statistics. This paper will walk through the evolution of the collaboration of the three areas, share success stories of their efforts and consider the challenges facing them in the future | adam dataset, clinical trial, cdisc | source poster source |

| 4 | A Comparison of Machine Learning Algorithms for Binary Classification of Free-text Fields Using SAS, R, and Python | Michael S Rimler | Clinical data collected via free-text fields are often difficult to use in analysis due to spelling or grammatical errors on data entry by humans, or simply stemming from differences in languages across global sites. Monitoring the data and querying sites to clean the content to support analyses is time consuming, even if the site is responsive and agreeable. Downstream processing of these data in preparation for analyses supporting clinical study reporting can also be quite challenging. This paper compares various methodologies for developing a binary classifier on free-text data. Machine learning methods in SAS, R, and Python are compared to an exact string search in SAS developed for 100% accuracy on the training dataset. A comparison of results of applying the trained models on the test dataset is presented, both individually and as combined methodologies | logistic regression, proc hpforest, training set, logistic distribution, regression analysis, data cleaning, feature engineering, type ii error, type i error, machine learning, adam dataset, unstructured data, fullstimer, proc hpsplit, proc freq, data mining, proc step | source presentation source |

| 5 | A Dynamic-automated Approach to Reviewing RTF Files | Hrideep Antony, Youying Yu |
This paper introduces "reviewfiles" utility which automates the review process of multiple RTF files. Combined features of SAS language, web scripting languages, and SAS Enterprise Guide (SAS EG) project functionality are used to build this utility. The current version offers a verity of file review capabilities such as summarizing the differences in the RTF files based on any changes to the contents, providing a refined version of changes to the contents based on a threshold value (eg. Search for changes to p-values > .5, etc.), creating a search result on all the files in the folder based on a key-value (eg. Search for file names and summary statistics relevant to a specific preferred term "Dizziness" etc. ), Extracting the first title of the RTF files and providing hyperlinks to the files for easy single-click access to the files. This utility not only makes the review of files easier but will also act as a means to control the quality of the overall deliverables | sas enterprise guide, macro definition, sas enterprise guide project, sample, ods xml, dataset | source presentation source |

| 6 | A Journey Through End to End Data Flow | Marcin Makowski, Stayce Murray |
Many organizations pursue digitization and automatization of the data flow in the clinical trial process. The creation of a platform that would encompass the whole end-to-end process from study concept to Tables, Figures, and Listings is a challenging one. UCB - a mid-size biopharma company has embarked on just that journey. Building a platform with an initial focus on risk management and protocol complexity assessments, the system's core functionalities hold the foundation to a digital protocol including the schedule of assessments, and protocol risk information. In further stages, the system was expanded to include functionalities around Quality Tolerance Limits monitoring and vendor risk management. Through this functional and data growth, a repository of digitized protocol information was created. This foundation and growth have empowered further development that focuses on digital data flow | clinical trial, machine learning, clinical research, crf, edc, artificial intelligence | source presentation source |

| 8 | A Real-world View of Cataracts | Jeffrey Headd, Walter Cedeno |
Cataract, an eye disease characterized by the clouding of the lens, currently affects over 25 million people in US. This number is projected to double by the year 2050 according to the NIH Eye Institute. To further elucidate drivers of cataract progression, we present an analysis of Real- World Data (RWD), which has gained wide acceptance in the pharmaceutical sector as a tool to understand disease progression, patient journey, unmet patient needs, and other areas. In this work, we apply methods in unsupervised machine learning, including K-Means, Mini-Batch K- Means, Agglomerative Clustering, Density-Based Spatial Clustering of Applications with Noise (DBSCAN), Interactive Clustering, and K-Modes techniques to Electronic Health Records (EHR) to explore the nature of variation within cataract patients | agglomerative clustering, cluster analysis, machine learning, euclidean distance, outlier | source presentation source |

| 9 | A Visual Tool to Aid Traceability | Jesse M. Pratt | Traceability is a critical component of any clinical research study. This paper discusses the use of interactive flow charts generated in SAS to trace outputs and analysis data sets to their various sources through the course of a study. Chart layouts are designed prior to any programming taking place, followed by the creation of a positioning data set and then generation of the chart itself using the Graph Template Language. The addition of HTML functionality results in a user-friendly, efficient, and interactive way to navigate across data sets and outputs. Illustrative examples highlight each step | data lineage, graph template language | source presentation source |

| 12 | Accessible Reporting by PROC STREAM | Charumathy Sreeraman, Samundeeswari Raja |
Reporting conformance to ethical and scientific integrity of clinical trials are monitored by various committees. Such monitoring is mainly performed by creating and reviewing the safety reports of a study. Availability of interactive and dynamic representation of the safety data in the form of tables and listings facilitates understanding of the data reported and eases the reviewing/validation process. These reports are commonly shared via email in printable PDF format. The best part of reports in this format is, they are easily printable on many different printers without adjusting margins or worrying about page breaks. PROC STREAM procedure is a powerful tool in a statistical programmer's arsenal because it enables easy generation of reports which clearly stream the, otherwise lumpy safety data. This paper shall discuss about the usage of PROC STREAM procedure, through simple coding for generation of various types of reports in PDF format |

| 16 | All about versioning - an intro into Distributed Version Control | Mark Bynens | Today as software developers, programmers or data scientists we need to work as a team and engage in collaborations to share our work. R, Python and other open-source software are globally used in pharma in various setups. As more open-source code has been developed, there is a huge need to collaborate and secure our code in a global environment. Repository management services have become a crucial part of collaborative software development. They can help software developers, programmers and data scientist organize their coding work, maintain quality, collaborate and share. This paper introduces collaborative software development, versioning, different types of version control systems, repository management services in general and will compare GitHub, Bitbucket, and GitLab | data science, excel | source presentation source |

| 17 | An Approach to Dynamic Data Visualization with dplyr DT and Shiny | Megan Kendellen, Nicholas Masel |
Timelines to develop regulatory documents are ever shortening, making manual review of large statistical outputs increasingly untenable. Manual review is also error-prone and hinders collaboration with cross-functional subject matter experts to select relevant data for in-text presentation. To address these challenges, we have developed an automated Data Visualization Tool. The tool converts data table outputs in Rich Text Format (.RTF) or .DOCX to a data frame and determines the number of columns within the table . Coupled with dplyr 's _at() variants, this provides a solution to dynamically process any table regardless of the number of columns. A Shiny user interface makes the tool end -user friendly. The result is a flexible t ool used to rapidly identify data points that exceed any desired incidence or are differentially reported across treatment groups at any desired threshold | proc freq, clinical research | source presentation source |

| 18 | An automated code translation approach in SDTM specifications using %translate macro | Hrideep Antony | This paper presents a standardized language specification writing approach that increases the overall efficiency of the SDTM programming. This SAS macro-based system invokes a %translate SAS macro which will scan through the SDTM specification document and identify all the variables for which the derivation can be translated to a SAS code and process those variables directly. It can be observed that around 50 percent of SDTM variable derivations involve directly reading raw data variables or a simple subset of data from the source. The %translate macro can also read the formats from control terminology and apply the formats to the data when applicable. The capabilities of this utility macro are currently being expanded with the ability to produce categorical and numerical summary statistics based on a one-line script which the users such as statisticians, medical writers, and content writers will be able to use to produce summaries effortlessly, without the need of any programming | macro variable, raw data, macro definition, cdisc | source presentation source |

| 19 | An Interactive Visualization Application for Patient-reported Outcomes with Spotfire | Matt Buckley | Interactive visualization tools provide researchers with a quick way to answer pertinent research questions and guide further analysis. These tools are especially helpful in the domain of Patient Reported Outcomes. This work demonstrates a TIBCO SpotfireTM application built for this domain. It highlights demographic data, clinically meaningful changes, questionnaire completion rates, and assessment measures by visit. It is also highly customizable, allowing users to filter for the population of interest and segment analyses by stratification variables. However, for large datasets and detailed analyses, Spotfire can become unresponsive and slow. The application detailed in this work was optimized for efficient calculations and low storage costs by pre-processing data in SAS. This makes the application responsive and quickly configurable | clinical trial, data visualization | source presentation source |

| 21 | An Update on CDISC-SEND Data Submissions to FDA | Jesse Anderson, Christopher Bartlett, Jennifer Feldmann, Valerie Gross, Alejandro Mankin, Qingying Lu, Kathryn Matto, Lilliam Rosario |
Over the past year, the US FDA received many electronic data submissions in CDISC-SEND format for nonclinical toxicology studies in new drug applications. Standardized data is used to quickly deliver key findings from nonclinical studies to pharmacology reviewers and aid in the efficiency of the review process. The FDA's KickStart team reviews a number of these CDISC-SEND submissions and reports on data quality issues identified during their review. The number and type of data quality issues identified in SEND submissions have changed over time, mirroring the success in industry-wide adoption of the SEND standard. If the industry addresses the most-frequently seen issues that may impact review, reviewers will be able to maximize the use of data submitted to the FDA for review | data cleaning, sample, cdisc | source presentation source |

| 22 | Analysis Studio: A Tool Framework for Supporting Regulatory Review | Andrea Arbelaez, Peter Glass, Derek Ahneman |
Regulatory reviewers in the Center for Drug Evaluation and Research (CDER) are responsible for determining the safety and efficacy of drug products before marketing in the United States. In the course of regulatory review, safety reviewers generate tables and visualizations for regulatory review documents. OCS Analysis Studio is a web-based application comprised of multiple interactive tools for the creation of tabular and graphical analyses ready to incorporate into these documents. Users are empowered to upload their own clinical trial data, customize the inputs according to their needs, and view the outputs, which change in real time according to user-provided criteria. A simple, intuitive, and consistent user interface across tools makes the regulatory review process more dynamic and decreases training time for safety reviewers. Outputs can be exported and saved as Word documents or JSON templates, allowing users to easily copy and paste analyses | shift table, audit trail, adverse events, treatment arm | source presentation source |

| 23 | Are There Any Better Options than SAS for TFLs? Yes, There R! | Niccolo Bassani | There's never been such a flow of interest towards the use of R in the pharmaceutical industry as in the past few years, although its practical use still seems to be hindered by several factors, sometimes due to misunderstandings (e.g. t he validation part) but also because of a lack of knowledge of its capabilities. Despite these bottlenecks, though, R is doubtlessly creating its own (larger by the day) niche in the industry. In this paper we will see how R can be used to create TLFs much like the current c ombination of PROC REPORT/PROC TABULATE and the ODS currently does, thus showing its power and capability to play an important role in our industry in the years to come, not as a replacement for, but rather as an alternative option to SAS |

| 24 | Are we there yet? Evaluating new non-EDC data sources for clinical trial submission feasibility | Vijay Pasapula | The current possibility that unlimited non-EDC sources of data (Wearables; Electronic Health Records; Smartphones; Custom Apps) will be available for collecting clinical trial data challenges the traditional methods of managing data for clinical trials. This paper discusses the work of the Data Engineering Project within the PHUSE Working Group; Educating for the Future; with a view to determine how best these data can be standardized and utilized for Clinical Submissions. This paper discusses how mobile technology data sources can be integrated (with the existing database), standardized and contribute to analyses that can then be utilized in submissions considering privacy and governance. Progress of the project will be presented during the conference with a chance to receive input from the audi ence | clinical trial, data governance | source presentation source |

| 26 | Assessing Non-inferiority and Equivalence from Survival Data | Chintan Arora, Parvee Kumar |
Non-inferiority or equivalence trials aim to show that the test drug is either not clinically worse than the reference (non-inferiority) or is clinically similar to the reference drug (equivalence) with margin calculation involved with both types of trials. There is ample literature available to asses non-inferiority or equivalence for continuous or categorical types of data. There are also copious options available in pre-defined procedures in statistical software like SAS and R; however, there is little written about options available in these tools to assess non-inferiority and equivalence specifically for survival data or calculating sample size for this type of study design. SAS has provided options to evaluate non-inferiority through PROC PHREG by calculating hazard ratio and corresponding CIs, but there are no options to evaluate non-inferiority if LOG-RANK TEST needs to be performed |

| 27 | Assessment of Machine Learning Methods in Coding of Concomitant Medications in Clinical Trials | Sanna Herrgård, Carla Gil, Ingrid Holst, John Holmer Nielsen |
In this talk we will discuss automation of coding of concomitant medications in clinical trials using machine learning. We have assessed performance of WHODrug Koda, developed by Uppsala Monitoring Centre (UMC), with data from 12 different studies across different therapeutic areas. We conclude that Koda would enable Novo Nordisk to increase automation level in the concomitant medication coding process from the current 62% to 79% when coding to Drug Code on the Trade Name level. Out of the 21% of the data that did not have a high certainty Drug Code prediction from Koda, 15% did have a single or multiple lower certainty Drug Code predictions which may provide additional value in the coding process. We observe that high certainty Drug Codes and ATC (Anatomical Therapeutic Chemical) codes predicted by Koda have a high conformance with Novo Nordisk coding with 96% and 94% agreement respectively | concomitant medications, machine learning, clinical trial, verbatim term | source presentation source |

| 29 | Automating Module 5 Packaging with Customizable Metadata | Dhananjay Chhatre, Kevin Miller |
In today's regulatory environment, study data packages included in regulatory submissions are being thoroughly reviewed and assessed for adherence to CDISC data standards requirements, and future audits focused on dataset and submission package development are the next logical focus area for inspectors. To mitigate audit risks and improve efficiencies and quality through automation, Gilead has embarked on a journey to develop a suite of utilities to automate Module 5 packaging while implementing Biometrics and Regulatory Affairs/Operations checks using customizable defaulted metadata as the starting point. This paper will focus on the strategic process and flow for how utilities work together, enabling automation and improving efficiencies while allowing for study statistical programmer customization for their specific study | regulatory submission, sdtm domain, cdisc | source presentation source |

| 32 | Automation of Submission Packages Quality Checks | Sendil K. Ramabadran, Anne-Sophie Bekx |
This paper introduces the automation tool for quality & compliance checking of clinical trial data submission packages to regulatory agencies. Up until now, submission packages were manually checked in the form of QC checklist for correctness, completeness and compliance to regulatory guidelines. This can be laborious and tedious job, with the possibility of human error. This automated tool acts as final gateway check or vetting tool before sending to regulatory/publishing group to build the eCTD. This also automates tedious work like checking all hyperlinks in PDF and XML files. By automating the checking and delivery of submission packages, handshaking between regulatory/publishing and data management/stat programming departments is also clear without any confusion across different therapeutic areas, functions (DM, STAT) and packages (SDTM, ADaM etc.) | proof of concept, data cleaning, cdisc | source poster source |

| 33 | Be the Master for a Master Protocol Study | Ke Xiao | As a new paradigm for clinical research, master protocol studies, either basket, umbrella, or platform trials, demonstrate increasing benefits and reveal promise especially in oncology drug development. The beauty of designing a master protocol study does not only lie in the fact that it can support the evaluation of multiple compounds with/without common controlled arms in different tumor types simultaneously, but also it provides the possibilities that allow patients to move from one investigational drug to another if deem appropriate. On the other hand, given these appealing features, it is also important to realize that compared with traditional clinical trials, to conduct such attractive master protocol studies, there are quite a few challenges on data collection, result presentation as well as analysis | adam dataset, clinical trial, randomization, clinical research, cdisc | source poster source |

| 34 | Best Practice for Interactive Analysis for Decision-making: An update from PHUSE Data Visualization Project | Xiangyun Wang, Zachary Skrivanek |
The goal of the best practice for interactive analysis PhUSE project is to evaluate how interactive visualization tools can be used as part of regulatory review process. How to balance the best of self-exploratory analysis with the rigor of regulatory requirements? What is the feasible framework to share interactive tools with the FDA? Is there a need to provide an industry-wide common user interface for regulatory reviewers to easily digest data from different organizations? How to address those and many other challenges facing interactive analyses in a regulatory setting is what we aim to explore. We will provide an update on regulatory and business considerations for different approaches and share our learning from an html interactive display pilot and Docker R-Shiny pilot with FDA. Next steps will be covered.

| 36 | Best Practices for Building and Testing Interactive Web Applications in R with Shiny | Kelly O'Briant | This talk will feature a gentle introduction to interactive web application development in the R programming language with two open source package libraries:shiny and shinytest. Both packages are used widely in the data science community and are actively maintained by engineering teams at RStudio, PBC. Shiny is an R package that makes it easy to build interactive web apps straight from R, without prerequisite knowledge of web development skills such as HTML, javascript and CSS. Shiny applications are particularly useful for developing dashboards and performing exploratory data analysis through interactive filtering and visualization. The shinytest package provides tools for creating and running automated tests on Shiny applications and the underlying code used to create them. Testing code is a general best practice for all forms of development, and Shiny applications are not an exception | data science, exploratory data analysis | source | 5 |

| 38 | Big Lab Data at the Fingertips of the Statistical Reviewers Using R Shiny | Mukul K Mittal, Sarah Cannon |
Laboratory data (LB) is one of the largest datasets in oncology clinical trials. Numerous parameters, tests along with multip le time points make analysis and visualization time consuming and cumbersome for both programmers and statisticians. To address these issues, we utilized the power of R statistical software to analyze the data and R Shiny package to make it a visual pleasure. Using interactive dashboard we can subset data as per parameter, test or the time range and visualize them for different cohorts/treatments and flags. This would give us flexibility to visualize data comprehensively or at patient level. These well-designed interactive graphs not only bring clarity to statistical results, they also save a lot of time for reviewers. In summary, R Shiny provides an elegant and powerful framework to turn complicated and large data analysis into interactive graphs at your fingertips | laboratory data, clinical trial | source presentation source |

| 39 | Building a Deeper Bench: Writing ADaM Specifications | Kristen Reece Harrington, Shane Rosanbalm |
In a world of silos, an organization can get by with having only a few individuals possessing the knowledge to write CDISC-compliant ADaM specifications. While silos do allow folks to become really good at one thing, it doesn't necessarily lead to a better quality study overall. A better model is to have the same programmers responsible for not just one aspect of a study (SDTM or ADaM or TLFs) but rather have them be responsible all aspects of a study (SDTM and ADaM and TLFs). This paper will focus on Rho's efforts over time to expand ADaM spec writing expertise from the core group of ADaM early-adopters to the broader programming group as a whole | adam dataset, data standard, cdisc | source presentation source |

To embrace the paradigm shift towards Central Monitoring, organizations must develop a structure that meets the needs of clinical trials operating today, but also supports the evolution and expansion of Central Monitoring as the primary means for monitoring data. This paper will outline key components necessary for organizations to create a foundation that facilitates the incremental growth and expansion of Central Monitoring. It will discuss the cross-pollination and integration of roles needed to assemble a nimble project team ready to meet the demands of a complex digital trial. Lastly, it will provide a scalable and cost-effective Central Monitoring model that harnesses technology and data science.

| 41 | Case Study: Integrated SDTM to Integrated ADaM to TLFs | Kishore Pothuri | The Integrated Summary of Safety (ISS) and Integrated Summary of Efficacy (ISE) are essential components of a successful submission. It can be very challenging and tedious to pool data for analysis from multiple studies without losing traceability, since similar information could have been mapped differently in different studies through diverse systems by various vendors, thereby putting compliance and harmonization at risk. What complicates the task further is that the number of studies involved can range anywhere from 2 to 50, or even more. There are multiple approaches to pooling and integrating study datasets for ISS and ISE analyses, namely ADaM Integration using study-level SDTM domains, ADaM Integration using Pooled SDTM datasets, ADaM Integration using study-level ADaM datasets | sdtm domain, adam dataset, sdtm programming, cdisc | source presentation source |

| 42 | CDISC 360: Using Biomedical Concept Metadata to Generate Case Report Forms and Dataset Definitions | Samuel Hume | This paper describes new metadata created by CDISC 360 and shows how to apply it toward the automated generation of basic study artifacts, such as ODM-based case report forms and a Define-XML specification. Specifically, it explains how an object-oriented Python program processes metadata from four sources to produce a Define-XML file. The four sources of metadata include: (1) Implementation Guide standards, (2) Controlled Terminology, (3) Biomedical Concepts, and (4) Templates. Biomedical Concepts and Templates represent new sources of metadata created by the CDISC 360 project. This paper uses visual representations of the metadata and logic to communicate the technical details. It also describes the role of the CDISC Library in providing developers access to this new metadata via its API. As an ongoing project, readers can influence these metadata constructs prior to final publication | clinical research, crf, cdisc | source presentation source |

| 44 | CDISC Library Try-out: From Implementation to Evaluation of the API | Roman Radelicki | CDISC Library promises linked data and a REST API to deliver CDISC standards metadata for software applications to automate standards-based processes. With my background as a programmer, my curiosity was immediately triggered during the presentation on the CDISC 360 project: a REST API (Application Programming Interface), linked metadata and biomedical concepts! In this paper, I want to share the journey of the CDISC Library implementation in one of our in-house developed tools. To test and demonstrate the implementation of the CDISC Library, we used our TS (Trial Summary Information) dataset creation tool. This tool was the ideal case study candidate because it is a standalone tool which makes use of the CDISC SDTMIG and CDISC CT data, without a major impact on other tools allowing quick deployment of the CDISC Library. The TS dataset creation tool enables the Clinical Data Manager to create the TS dataset for a trial, necessary for submission to the authorities | controlled terminology, trial summary, sdtmig, rest api, excel, cdisc controlled terminology, cdisc | source presentation source |

| 46 | Challenges and Solutions While Mapping Laboratory Data | Ratheesh Gunda | Poster: In Oncology studies it is quite common to get complex laboratory data from different labs with different standards and measurements within similar tests. There can be variations in normal ranges, collected units, and connotations for collected results. Given the length of a typical Oncology study it is can also be challenging to keep up the changes in standards like NCI, CDISC etc. Lab domain is one of the main safety data sets and Oncology studies contain a myriad of different types of data when compared to a regular study which primarily contains only Hematology; Chemistry; Pregnancy data. Also, each patient will have numerous tests per visit per time point. When not planned properly we will face a lot of confusion when trying to map this data into analysis domains and eventually output into TLFs | missing value, laboratory data, cdisc | source | 1 |

| 48 | Code Generator to Check Truncated Values in Derived Datasets | Proma Mukherjee | An important part of dataset programming validation involves handling of SAS log messages like overwritten variables, missing values, etc. Since there is no specific log message for character variable truncations, the usual validation method is manual scanning or spot checks of datasets. The intent of this paper is to provide a robust macro script which can be used in dataset codes to check for possible truncation of character variables. It achieves this by checking the length and value of character variab les in the derived and source datasets. The required inputs are the source/derived dataset names which generate 'truncate check datasets'. These macro-generated datasets contain the character variables and their maximum length in a single observation which can be visually glanced through to check for possible truncations | character variable, macro variable, data cleaning, numeric variable | source presentation source |

JumpStart is a FDA Center for Drug Evaluation and Research (CDER) service which provides data quality and data analytic support to reviewers. Since 2013, the JumpStart team has assessed the data quality of Study Data Tabulation Model (SDTM) data for over 170 New Drug Applications (NDA) and Biologics License Applications (BLA) using automated tools. The JumpStart data quality assessment reviews the composition and quality of clinical trial data to identify potential issues and errors that may affect a review. As part of the service, the JumpStart team investigates these findings and helps determine their potential impacts for review teams. This paper discusses some of the common findings from the JumpStart investigations that most impacted application reviews. We share these findings to inform applicants of the identified data quality issues to encourage them to submit higher quality data in the future, thereby increasing the efficiency of the review | adverse events, data cleaning, clinical trial, cdisc | source presentation source |

| 51 | Complexities in Adhering to Data Standards for ISS NDA Submissions | Vidya Muthukumar | Regulation of new drugs in the US has been based on the New Drug Application (NDA). NDA application is the process by which drug sponsors, such as biotech and pharmaceutical companies, propose that the FDA approve a new drug for commercialization. Drug sponsors use the services of Contract Research Organizations (CROs) to help with the complex NDA submission process. The Integrated Summary of Safety (ISS) is a section of the NDA that provides a complete review of safety information through meta-analysis and pooling of data from clinical trials performed with the study drug. The ISS is useful to, 1) Identify rare and/or unexpected trends in patient subgroups, 2) Improve the precision of results with a larger population size by integrating studies, 3) Reach stronger, more defendable statistical conclusions. This paper demonstrates a recent ISS NDA submission to the FDA and the complexities surrounding the process of adhering to data standards | adverse events, sdtm domain, cdisc | source presentation source |

| 56 | Data Compliance: Hidden Benefits | Priyanka Adusumilli | The pharmaceutical industry is currently spending a large amount of money updating the CDISC SDTM submission packages according to FDA standards. Once study data is deemed ready for submission by a vendor, most sponsors expect the compliance checks are completed, merely to update the data for that study. However, those same findings from the compliance checks can be used to identify bigger issues with the overall collection strategy. John Powell once said, "The only real mistake is the one from which we learn nothing." Addressing the issues within the individual study for compliance checks solves the immediate problem, until the next study comes along and the same findings are prevalent. Being able to learn from these findings and use them in a positive manner beyond the individual study can help create efficiency and provide a more transparent data transformation strategy that will be in line with the FDA's expectations | raw data, data transformation, cdisc | source | 3 |
| 57 | Data Exchange in Clinical Trial - Programming Perspective | Chao Wang | Data exchange is heavily intertwined in the development and procedures of clinical trials. A large component of data exchange in clinical trials involves programming, and the perspectives of programming professionals. Programmers are responsible for maintaining Clinical Data Interchange Standards Consortium (CDISC), controlling terminology and cleaning related metadata for scientific and clinical use. Challenges that arise during the process of producing, managing and exporting the data include data accuracy and data security, among others. These challenges are made more difficult when working with multi-regional studies, different operating systems, and data obtained from different sources such as the Electronic Data Capture (EDC), Study Data Tabulation Model (SDTM) and Analysis Data Structure (ADaM). These data are finally compiled into clinical reports (tables, listings, and figures) that are then exchanged | clinical trial, raw data, sdtm domain, cdisc | source presentation source |

| 59 | Data Review of RECIST Criteria using ML/AI A Proof of Concept Example | Priya Gopal | Machine learning (ML)/Artificial Intelligence (AI) provides the ability to learn from data patterns and make decisions without the need for explicit programming. In oncology clinical studies, data management/medical review team verifies the tumor measurements and corresponding assigned RECIST criteria using manual approach to determine quality of the response data entered by the sites. Depending on the size of study population and complexity, the review process may involve additional resources and time to check for each data point in the study. This paper focuses on a proof-of-concept (POC) of how machine learning (ML) algorithms/Artificial Intelligence (AI) could help increase efficiencies with review and cleaning process of tumor data. Realistic simulated data containing tumor measurements and corresponding RECIST response values are synthesized and used to train the various algorithms and neural networks in identifying the data patterns to infer RECIST criteria | neural network, data cleaning, imputation, missing value, machine learning, artificial intelligence, network optimization, training set | source presentation source |

| 62 | Data Standards Used for Electronic Submission of Real-World Evidence in New Drug Application (NDA) | Nicole Thorne, Kathy Wu |
The current standard of care therapy for the disease under study, is shown to have a low response for subjects with the specific tumor biomarker alterations we are targeting. Using a real world matched clinical and genomic dataset of patients with the disease, we explored the predictive value of this specific tumor biomarker alteration to the current standard of care therapy. At the pre-NDA meeting results of these real-world analyses were presented and decided to be submitted as a white paper, to be included in the submission. At the same meeting, the Federal Drug Administration (FDA) requested that the data to support this analysis be included in CDISC format. This paper covers our experience in submitting the Real-World Evidence (RWE) data in CDISC format, including the ADaM structure we used, other factors impacting our decisions, and our experience with a FDA technical walkthrough | clinical trial, overall survival, raw data, adam dataset, concomitant medications, sdtm domain, cdisc | source presentation source |

The Center for Biologics Evaluation and Research (CBER) within Food and Drug Administration (FDA) intends to receive Standards for Exchange of Nonclinical Data (SEND) datasets in future submissions. However, implementations currently defined in published and planned SEND Implementation Guides had not been evaluated regarding data models needed for representing certain study types (including study design) or endpoints typically received in a CBER submission. The SEND for CBER team was formed to evaluate endpoints related biodistribution, immunogenicity, test article characterization and hybrid activity/safety trial designs with the current SEND domain models available to understand gaps and possible new requirements. To address the intention of CBER, a team has been developed and project work strategy followed to evaluate essential SEND data tabulation needs for supporting CBER submissions | liquidity gap, controlled terminology, data standard, cdisc | source presentation source |

| 69 | Digitalization of Clinical Study Report (CSR) Tables and Listings for Cross-report Verification | Iraj Mohebalian, Michael Badlani |
Large-scale efficacy clinical trials generate numerous table and listing reports in PDF or MS-Word format for inclusion in Clinical Study Reports. The importance of data accuracy, frequency of generation and sheer length of reports combined, make their verification crucial, time-consuming, and prone to human error. This paper presents the framework and one of the tools we have developed at Bayer to automate a number of verification checks that help improve the quality of our TLF deliverables by performing various consistency checks for every study deliverable. This is done by digitalizing and storing the contents of the reports to a standardized cell-based data repository with each cell stored having multiple properties associated with it. We present specific examples of our tool using mock data from a Phase III clinical trial study and show the benefits such a tool can have in improving the quality of the deliverables | clinical trial, sas log | source presentation source |

| 72 | Dual Roles: I'm not just a programmer! | Laura Williams, Hunter Vega |
Any successful business will be able to hire and retain great employees. One critical component to retaining those employees is establishing a focus on professional development that originates with the company leadership. Contract research organizations (CROs) are no exception. One unique type of professional development occurring in our organization is the opportunity for dual roles, not only in management but in operational areas. When an employee has reached a senior role in his/her department, they may be interested in ways to transition into roles with more leadership potential and/or a demand for higher-level technical skills. The focus of this presentation will be on the ways statistical programmers can work in dual roles and expand their skill set, as well as support different operational groups and become involved at the onset of project planning | statistical programmer, clinical programming, data science, clinical trial | source presentation source |

| 75 | Efficacy ADaMs in Oncology - Step by Step (Dataset by Dataset) | Ilya Krivelevich, Ran Xie |
The CDISC ADaM team has designed the Analysis Data Model (ADaM) standards to support submission to regulatory agencies such as the U.S. Food and Drug Administration (FDA) and Japan's Pharmaceuticals and Medical Devices Agency (PMDA). Pharmaceutical companies are required to follow the ADaM st andards for analysis datasets to ensure a successful submission. The design of analysis datasets is generally driven by the scientific and medical objectives of the clinical tria l. In oncology, efficacy endpoints can be classified as 'w ith' or 'w ithout' censoring. ADaM guidance recommends storing analysis results for censoring parameters and non -censoring parameters separately; therefore, there is a need to have tw o ADaM datasets w ith derived subject-level parameters. This article sheds light on creating analysis datasets for oncology efficacy (specifically for solid tumors) w ith step-by-step techniques and examples.

| 78 | eSource Arising: Clinical Data Automation Possibilities Beyond Data Capture | Sofie Stynen, Annelies Van Zeveren |
When implementing the 1st generation of eSource system at SGS, the focus was on facilitating data capture and converting clinical data directly to SDTM, making eCRF redundant. After getting familiar with eSource, we are now ready to use our gained knowledge and expertise and take eSource clinical automation to the next level with the 2nd generation of eSource system. This paper will highlight our acquired insights and challenges faced from both systems resulting in improved efficiencies. Focus on standardized data and the use of code lists to convert easily to SDTM are key for efficiencies. With a proper test environment set up in the 2nd eSource system, it is now possible for data management to enter dummy data, making it easier to set up SDTM conversion. Data visualization and accessibility have improved significantly, and the new query management seems to allow for shorter data cleaning-timelines | sample, clinical data, clinical trial, data governance, laboratory data, adverse events, cdisc | source presentation source |

| 79 | Evolution of Clinical Data Disclosure and Transparency | Sneha Paradkar | The pharmaceutical industry has put greater focus on posting results of clinical trials for public disclosure. Data transparency is an important aspect of clinical research as it helps in enabling evidence-based decisions in medicine. Clinical data disclosure and transparency is of utmost importance due to legal obligations and compliance factors associated with data disclosure. If sponsors or research organizations do not disclose clinical trial results on time or fail to post results at all, it may lead to misconduct or data fraud in clinical trials, also posing legal penalties to the organization. Publishing results from clinical trials helps in reducing the global costs of drug development. In the past few years, there has been a significant change in the way clinical trial results are posted | clinical trial, clinical data, pharmaceutical industry, clinical research | source presentation source |

SDTM mapping process is redundant and time consuming, which always required a CDISC-SDTM Analyst intervention while creating the mapping specification in order to meet regulatory requirement. Automating the mapping process by utilizing emerging technology such as Machine Learning will effectively reduce the manual efforts and increase the quality of conversion study by study. System which uses Natural Language Processing (NLP) logics with continuous learning, eventually will help to predict not only the standard domain mapping but also will learn the creation of custom domains and will perform those mappings automatically in similar situations. Outcome of using this emerging AI technology, is gearing up the standards mapping and encouraging the effective use of SME's time.

| 86 | Fill Patterns to the Oncology Plots Using SAS | Dharmendra Tirumalasetti, Vikram Chanduri |
In Oncology trials, it is very common to produce the plots with color coding based on grouping variables like Disease Responses using PROC SGPLOT. However, in some trials, there will be a requirement to use both fill patterns and color to distinguish between multiple group variables. Fill patterns can be applied to any plot using an option FILLPATTERN in SAS v9.4M5 or later releases. However, there is no such option available in the previous versions of SAS. In this paper, we will present how one can generate the fill patterns and colors to the plots that are widely used in Oncology trials (e.g. Waterfall plots) using the power of PROC TEMPLATE and PROC SGPLOT in SAS versions before 9.4M5. We will also provide some examples of the plots that will help the end user in reviewing the |

Companies have been creating TFLs using SAS for decades. More recently, R usage has increased for TFLs. As this trend continues, knowing R is only a first step. There are many challenges both in coding and infrastructure which must be foreseen to replicate the results produced by SAS. We will present examples of issues which arose as our department started using R for some TFLs. Examples include sorting and rounding differences, derivation of p-values and LS Means, producing submission quality reports, and handling version updates. Some resolutions are based on knowing the different defaults SAS uses rather than R. Others are based on creating R functions to work around different assumptions that R and SAS make. Still others depend on users being aware of the different ways the languages work. We will present one use-case where we still have not figured out how to replicate the values in R | proc step, proc freq, fisher exact test, missing value, exact test, character variable, numeric variable, proc report, proc sort, box plot | source presentation source |

Poster: Swimmer plots provide the capability to quickly and intuitively understand the clinical progression of a subject during an oncology trial, as well as visually comparing individual subjects on various regimens. A variety of time to response variables can be plotted to give the viewer an easy-to-understand graphical overview of a subject's timeline, including tumor status milestones, duration of response, and prior/concomitant therapies. In addition, significant other occurrences such as adverse events of special interest can be identified and temporalized. Unlike other types of plots, a swimmer plot can also indicate the subject's eventual disposition or survival status. New PROC SGPLOT and SGRENDER options for SAS 9.4 are available to further identify and highlight specified events.

The CDISC SDTM metadata, outlined in the SDTM Model, are used for submission of data from both clinical trials and nonclinical studies. Until recently, many of the Pinnacle 21 validation rules were assigned for both SDTM and SEND domains when in some cases, a specific rule did not apply for SEND data as outlined in the SENDIG. Over the past year, the SEND rule set ha s been refined through the modification of existing rules, removal of others and creation of new rules. All rules are based on either an FDA Business rule, an FDA Validator rule, or CDISC rules.

In this paper, I am going to illustrate how SAS and R can complement each other for creating health authority submission package. R was involved in preparing for eSUB Module 5 in one of the submission I worked on before. This approved that R can make the products with submission ready quality. Additionally, making use of the advantages from each tool can provide an excellent work for Health Authority's requests. Recently, I was involved in an EMA request for exploratory analysis, where SAS was used to implement the part of step-wise modelling selection and R markdown was used for the rest part of exploratory analysis. Therefore, detecting the right tool for right situation can provide us the good quality, clear documentation and efficient manner for submission | regression analysis, forest plot, feature selection, clinical trial, pharmaceutical industry, data science | source presentation source |

| 96 | Handling Duplicate Records in SDTM for Effective Resolution and Explanation in Data Submission | Varun Debbeti | One of the challenges of SAS programmers is handling duplicate records in the raw/SDTM data. These are observed due to unclean data or programming inefficiency or due to the necessity to collect multiple results for special analytical or statistical purpose in the trial. In some cases, these are much harder to manage and can complicate analysis by producing unexpected outcomes and programming delays. This paper presents the background to identify different types of duplicate records by using the concept of Natural Keys and Surrogate Keys described in the SDTM IG 3.2. It also discusses FDA business rules, FDA Validator rules, corresponding Pinnacle21 (short form P21) Validator rules and warnings in P21 report that covers the duplicate records. The background is used to classify the most common types of duplicate records in to 5 categories. This paper then provides examples and prescribes standard set of actions to resolve the issue in each category | natural key, key, surrogate key, sdtm domain, variable list, missing value, data validation rules, data governance, reviewer guide, cdisc | source presentation source |

| 97 | Handling Missing Data in Clinical Trials: Techniques and Methods | Pennidhi Karlakunta, Naveen Kommuru |
The reliability and interpretability of results from randomized clinical trials are greatly influenced by the quality of data. Missing data in clinical trials can be a serious problem, especially in randomized trials where missing data could produce biased estimates and compromise inferences. The preferred and most satisfactory approach to address missing data is to identify ways to prevent it. However, missing data are ubiquitous as some of the trials could span over months or years. Since each trial has its own set of design and measurement characteristics, currently no universal method for handling missing data in clinical trials. This paper will present programming techniques and methods to handle missing data with a major focus on multiple imputation | missing value, imputation, multiple imputation, sample, clinical trial, proc step, treatment effect, likelihood function, proc mi, inferential statistics, adam dataset, confidence interval, maximum likelihood estimation, sensitivity analysis, proc means, cdisc | source presentation source |

| 105 | Incidence Rate - Incidence Proportion Prevalence Rate and Other Related Statistics | Nadiia Pukhliar | There is a tangle with incidence related statistics in clinical trial reporting. In the analysis of Adverse Events one often uses "incidence rate", but actually means "incidence proportion". Whereas incidence density rate is the same as incidence rate with only one qualification: denominator is based on subject-time at risk. The algorithm for time at risk calculation is completely different for Adverse Events analysis compared with PD or death analysis. For Adverse Events analysis, FDA uses terminology "incidence rate" alongside with "reporting rate". How to sort out which statistics name implies the correct object is an open question. The choice of inappropriate algorithm leads to undercounting number of events. Statistics for incidence can be queried for both safety and efficacy analysis. While working on TLFs for reporting, we found out that there are various approaches and different meanings for the same statistics depending on the context and analysis needs | adverse events, proc sql, create table, group by, proc step, order by, proc freq, clinical trial | source presentation source |

| 108 | Interactive Adverse Event Data Visualization Using R Shiny | Aditya Rachoori, Mukul K Mittal |
AE data is critical data in drug discovery process, monitored for the patient safety and to take critical decisions regarding continuation of subjects in clinical trial. Reviewers look for parameter such as treatment emergent, seriousness, relatedness and toxicity grade. The traditional AE reports consist of basic summary tables and listings. It is difficult to detect AE patterns in a table presentation. Interactive visual analytics present a useful alternative to static outputs for exploring safety data and present a great opportunity to enhance evaluation of drug safety. In this paper we would use R -Shiny application to create interactive dashboards based on different parameters, which would help the statisticians to have comprehensive view of the Adverse events as well as they can a lso look at more granular level. Overall R -Shiny app would provide the detailed AE information at patient level/study level as interactive graphs and tables | adverse events, trial elements, system organ class, heatmap, ctcae grade | source | 9 |

Health is not something that happens a couple of times a year when you visit doctors. Health is something that happens every day. It is happening right now. It is cumulative of choices, lifestyles. Artificial Intelligence (AI) is making its way into the realm of clinical trials. While a lot of discussions seems to be centered on clinical trial recruitment and using AI to mine electronic medical records (EHRs), but it seems to only scratch the surface. Experts predict monitoring drug adherence, pre-emptive risk monitoring, decision-making, diagnostics, and process optimization are some of the other areas where the technology is expected to make an impact in future. In this paper, we will explore the benefits of SAS Viya from a machine learning and AI perspective.

| 113 | Let Us Trace Back to the Beginning from the End | Madhusudhan Reddy Papasani, Swathi Kotla |
Integrity of regulatory submissions relies on traceability, allowing regulators to check source data and understand the processes involved in the transformation of data, to the analysis results. CDISC standards, along with the Define-XML, are interconnected and designed to provide relationships between analysis results, analysis data and SDTM datasets. In this paper, a discussion of data standards and traceability is reviewed using an analysis table from an oncology Overall Survival (OS) analysis to explore traceability from the analysis results back to the case report form (CRF) collected data. As part of this process, interrelationships between analysis results (AR) to analysis results metadata (ARM), ARM to ADaM datasets, ADaM datasets to SDTM datasets and finally SDTM datasets to the CRF will be presented, traced and highlighted here in the same way a regulatory reviewer would trace results to the source data in a submission review | adam dataset, sdtm domain, overall survival, log-rank test, rank test, temporary dataset, annotated crf, data standard, clinical trial, regulatory submission, raw data, data science, randomization, cdisc | source presentation source |

| 114 | Let your SDTM or ADaM SAS code update itself whenever the Specs change | Joseph W. Hinson | Statistical programmers typically use SDTM and ADaM specifications laid out in an MS EXCEL workbook as a guide for developing SDTM or ADaM dataset SAS programs. But this "Specs" document usually undergoes several changes throughout the study lifecycle. Often the changes are made by the lead programmer without notifying production and validation programmers. The paper uses PROC SQL and the PE domain as examples for updating the variable attributes LABEL, TYPE, and FORMAT whenever the dataset creation program is run. This is made possible by embedding macro calls in the PROC SQL code. The paper describes how the macro calls use DOSUBL and %SYSFUNC to perform virtual "typing" of code keywords in the PROC SQL code. Such a dynamic code update technique can make SDTM and ADaM programs instantly updated whenever run, thereby reducing coding time as well as preventing mismatches between dataset variable attributes and their specifications |

Demanding large amounts of both statistician and programmer time, it is an expensive process that grows more costly as the quantity of required metadata increases. The design phase of the dataset specification process, in particular, appears ripe for automation. Previously, Rho began work to leverage historical specification data to generate recommendations for programmers entering ADaM specifications for new studies. Here we build on the text mining methods introduced in the previous work by applying creative data preparation, feature development, and machine learning models to the predictive task.

Comparing individual datasets might be easy but if there is a need to compare all datasets at once, definitely it would be a challenge. To overcome this challenge, we can take advantage of macros and automation. This paper illustrates a group of macros which will helps programmers to compare all the datasets of libraries at once and create the report which contains mismatches or updates of datasets w ith clear explanations.

The annotated Case Report Form (aCRF.pdf) is a crucial component in a data submission package. The variable and value annotations on the aCRF are linked to PDF page references in the define.xml, allowing reviewers to quickly associate submission data with the collection forms. For that to work, aCRF annotations and define.xml origins must be consistent. Aligning CRF page references in the define.xml with the aCRF annotation, and keeping them aligned, is an arduous task if handled manually. In this poster, we will share a programmatic approach that extracts CRF annotations (including pdf page numbers) into a SAS dataset. Previous literatures suggested exporting CRF annotations in FDF format. However, we found that exporting as XFDF format is more user-friendly because of its XML-like nature. We will share a CRF annotation schema that allows for efficient extraction by SAS programs | dataset, crf, cdisc | source poster source |

| 140 | Programmer to SME - Career Game Changer | Divya Cetlur, Ephicacy Lifescience |
Imagine an intersection in a Venn diagram, where one circle represents "Programming" and the other "Management" - the intersection is what we would call "Subject Matter Expert (SME)". Subject matter experts are individuals, who are competent to perform the work hands-on as well as manage the work - gauging the complexity and time required, thus enabling effective study management. SMEs shoulder major risk in successful delivery and hence, have become popular touch points for the leadership or project managers in the recent times. Their work revolves around 3 major productivity targets: a) complexity of the task, b) resource/task allocation to individuals in the study team, c) quality and timeliness of the tasks/report objects delivered. This paper will discuss few career-game changing scenarios and pointers to evolve from a programmer to an effective SME in today's programming world | mock shell, clinical trial | source presentation source |

| 142 | Quarterly Safety Reporting: Timely Analysis of Clinical Safety Data Using Qlik Sense Software | Yvonne Denkins | FDA guidance strongly recommends a process for reviewing, evaluating, and managing accumulating safety data within the clinical data base at appropriate intervals (21 CFR 312.32(1)(i))1, 2. To meet client requests for review of safety data per agency guidelines, Clinical Scientists (CS) at IQVIA Biotech created and developed a robust process for quarterly safety reporting. Clinical Science and other team members review study data quarterly using a validated Qlik Sense software platform. The resulting Quarterly Safety Report (QSR) is prepared as a stand-alone document showing case report form safety data using tables and graphics. Any anomalies, trends, and safety signals found are reported to the client and if needed, regulatory agencies. The IQVIA Biotech Qlik Sense software platform is a visual tool that incorporates data from multiple sources into a user-friendly, interactive, dashboard environment | clinical data, data review, vital signs, adverse events, clinical trial | source presentation source |

| 143 | R & Python for Clinical Workflows | Philip Bowsher | The statistical programming space is evolving. Many universities and programs are educating students about Clinical Data Science. Moreover, the field is popular among recent graduates. R, Python, SQL and Javascript are important programming languages within the Clinical Data Science toolbox. For years, people have wondered which language will take the top seat but It is clear now that a new topic has taken focus… Interoperability and the capability of these different languages to work together harmoniously. If you review any data science job application, you will likely see R and Python listed together among the technologies to know. The information below will focus on the interoperability of the top 2 programming languages in the data science space, R and Python, and how they can be combined to achieve great results for your clinical workflow | data science, deep learning, statistical programmer, machine learning, clinical research, clinical programming | source | 13 |

| 147 | R syntax for SAS programmers | Max Cherny | Making the transition from SAS programming to R programming can be quite challenging, especially for SAS programmers who have never coded in an object- oriented language. However, learning to code in R does not have to be difficult for those already fluent in SAS. Both languages provide similar functionality, with the main difference being the syntax required to accomplish the same objective. This paper provides a side-by-side comparison of R and SAS syntax, using examples of a clinical programmer's typical SAS code adjacent to the corresponding R syntax. These easy and reusable examples can function either as stand-alone programs or as starting points for further acquisition of R fluency for the SAS programmer | character variable, numeric variable, sas programmer, sas syntax, proc step, proc transpose, sas programming, data science | source presentation source |

Over the past decade we have helped dozens of life sciences clients identify, design, and implement their statistical computing environment (SCE) leveraging the best of breed technologies and optimizing their processes. During the past few years we have noticed a higher level of scrutiny by regulatory authorities around the clinical data lifecycle relative to an SCE. Our clients have been given formal warnings around topics such as unauthorized access, lack of traceability, and overall data integrity. These issues and how the regulatory authorities choose to enforce them could cause significant issues for pharmaceutical companies and delays in submission costing millions of dollars | data integrity, 21 cfr part 11, life sciences, audit trail, clinical data, data cleaning | source presentation source |

| 158 | Spotfire Patient Profile Graphs: An Abridged Effective Approach Using Scripting Languages | Anish Kuriachen | The patient profile plots play a significant role in the monitoring and reporting of subject safety information from the onset of a clinical trial. Traditional patient profile plots are created based on safety data such as lab results, vital signs, drug exposure, etc. The classic patient profile graphs are usually plotted on the same x-axis using the duration of the subject in the study as the x-axis reference range. This approach occasionally leads to illegible graphics output, especially if the study has several time points or visits that collect safety information. In addition to this challenge, the traditional patient profile requires the corresponding listing outputs to interpret the subject safety profile, since graphics by itself may not express the whole story about the subject.

| 159 | Standardization = Automation: A Journey from Dataset Specification to SAS Code | Anastasiia Khmelnytska | The beauty of standards is in the fact that well-defined structure screams automation. Creating datasets according to CDISC guidelines has never been easier with the macro that transforms your dataset specification into SAS code. It will make you forget about manually defining variables' attributes and parameters once and for all. The step by step guide will also cover the mappings of standard variables and parameters defined in the specification. In this paper we will discuss several approaches to creation of dataset specifications that can be used effectively for automatic code generation. Whether you are creating SDTM datasets from raw data, or mapping SDTM data to ADaM standards, with this advanced technique, you will be able to create different datasets with a single macro call - all you have to do is to choose your parameters wisely | macro variable, data step, proc step, excel, proc contents, proc format, proc import, controlled terminology, cdisc | source presentation source |

SUPPQUAL datasets were designed to represent non-standard variables in SDTM tabulation data. There are many recent discussions about whether the SDTM Model should allow the addition of non-standard variables directly into General Observation Class domains instead of using SUPPQUAL datasets? However; there is still a lack of implementation metrics across the industry to understand actual utilization of SUPPQUAL datasets. In this presentation we will summarize metrics from many studies and different sponsors to produce an overall picture of utilization of SUPPQUAL datasets by the industry. We will analyze commonly used SUPPQUAL variables for being potentially promoted to standard SDTM variables. Also, we will provide and discuss examples of correct and incorrect utilization of SUPPQUAL datasets in submission data to understand if the industry is ready to switch from SUPPQUAL datasets to non-standard variables? | trial elements, adverse events, regulatory submission, data cleaning, cdisc | source presentation source |

Consistent representations of the collected data are important for internal data review as well as regulatory submissions. Many companies have developed standard analysis Tables, Listings and Figures, and PhUSE also provides shells that can be used to represent the data. Generation of standard TFLs usually involves pre-defined programs or macro calls. Two common approaches to for the generation of Listings and Tables are: 1. Content driven utilizing PROC REPORT or Tabulate and providing extra layout information 2. Layout and variable content is used to fill an output in a cell by cell fashion With organizations using a metadata repository to manage their standards, this MDR can also be used to manage the content required to automate the generation of TFLs, providing full data traceability |

| 165 | The Elusive Goal of Automation in SDTM Mapping: A CRO perspective | Sridhar Vijendra, Ephicacy Lifescience |
Much has been proposed and experimented with automating SDTM mapping to convert raw data (legacy/CDASH format) to CDISC SDTM standards with no or minimal human intervention. This is no easy task given the complexity and variety of studies, constantly evolving standards, and the struggle to keep up with demanding timelines. Stakes are higher in a CRO (Contract Research Organization) environment where additional variables sneak in to make SDTM automation a near impossible feat. One of the ways to automate SDTM mapping is to standardize CRF pages using a metadata repository (MDR) that allows usage of standardized mapping programs. The other option is to use machine learning and natural language processing, but this is yet to see effective implementation in practice. In this presentation, we look at SDTM mapping needs for our client to find an option that minimizes human intervention to speed up turnaround with no compromise on quality | sdtm programming, raw data, machine learning, cdisc | source presentation source |

A fully randomized clinical trial is necessary to conduct unbiased and objective research. However, randomization can also hide some relations between study subjects that could be interesting to the investigator. Classification and similarity techniques are a powerful tool to discover these lost relations. Among these, general linear models help to find the effects between the treatment groups and within treatment groups. This paper provides an example of General linear model, ANOVA (Analysis of Variance) for different treatment groups.

| 168 | The JumpStart Traceability Assessment | Tejas Patel, Sarah Ferkov |
Analysis Data Model (ADaM) datasets are frequently used as primary data for U.S. Food and Drug Administration (FDA) clinical reviews. Tracing ADaM data to its Study Data Tabulation Model (SDTM) source allows FDA reviewers to assess the relationship between the original and the derived data. The SDTM to ADaM Traceability Assessment investigates SDTM Demographics, Adverse Events, Laboratory, and Vital Signs datasets and compares them to their ADaM counterparts. The JumpStart analyst uses SAS programs and various display tools such as JMP to identify and evaluate differences between SDTM and ADaM. The customized SAS programs are run at the study level and matched to the submitted variables. Similarities and differences for key variables are then summarized and presented to the clinical reviewer.

| 170 | Titles Are a Programmer's Best Friend | Gregory Nunn | When creating outputs for clinical reporting, much of the information a Clinical Programmer requires is contained within the title. An experienced programmer will break the title down into components and use these components to visualise the output. So why don't we use these components to produce the output? This paper looks at building a bridge between an output title and an existing standardized reporting macro. By breaking the title down into recognisable components that can be used to populate macro variables, we can produce programs which create a 'best guess' at the output, alongside editable SAS code. Furthermore, by utilizing methods such as artificial intelligence, these programs could be adapted over time incorporating changes made to the tables.

| 171 | Untangling the Subject Elements Domain | Christine McNichol | The Subject Elements (SE) domain is unique and challenging in its sources and mapping. Without much encouragement, a map of the sources, derivations and interaction between records in SE can start to look more like a tangled mass of spaghetti than common linear SDTM mapping. Why is this? SE can have multiple sources for the data points needed to derive each element's start and end. Compared to other domains, SE also has a good deal more direct correlation to values in other domains. For successful implementation, it is critical to understand SE's purpose and requirements, the unique mapping path from source to SE and how this differs from other common domains, the steps needed to successfully derive SE, and programming methods that can be used. This paper will explore the inner workings of SE and explain how to successfully create SE one manageable bite at a time | raw data, date variable, sdtm domain, sdtm programming, randomization, medical history, cdisc | source presentation source |

Validators can check if nonclinical studies submitted in CDISC SEND format meet FDA business rules, FDA validation rules, CDISC conformance rules and PMDA's Define.xml rules as applied for SEND. However, these validators cannot check if the SEND Trial Design is modeled correctly according to the Study's design w ith sufficient granularity. For example, if a Latin square study is coded in SEND as a parallel design, the SEND dataset cannot be reviewed or analyzed. Since SEND datasets are prepared separ ately using a CDISC trial design, the SEND data set should be checked to ensure it will generate the same summary results as listed in the audited study report. Manual "spot checks" are insufficient and risky.

We developed a visualization scheme for fifteen key metrics, some of which are part of PHUSE's common Data Reporting Metrics1. In order to maximize the effectiveness of these visualizations, a dashboard was created using a popular tool, Tableau. Equally as important, and as difficult, was the development of a process surrounding the use of this dashboard.

Plots created using ggplot2 are built using a layered approach. Users can view the work in progress without needing to complete the final work. The code can be developed and executed one layer at a time and adjusted as needed. The purpose of this paper is to utilize the ggplot2 package and few add-on packages to produce multi-layered plots. Most of the examples require just a few lines of code. Oncology tumor response data will be used as input. Users can easily visualize the data and the outcome of tumor assessment over time, using information such as tumor size, new lesion, overall response, etc. with different plot arguments (ex: symbol, color, size, etc.). Many default settings of ggplot2 functions can generate high-quality plots. The examples illustrated in this paper will show that ggplot2 syntax is intuitive and easy to follow.

Volcano plot is yet another two-dimensional space saving scatter plot to graphically present measure of strength versus significance of a statistical signal. It may be used to interpret multiplicity adjustments to reduce false positives. When events (AE) are displayed by time interval, it illustrates how risk changes over the course of a trial. It is widely used in genomics to analyze microarray expression data etc. It is a powerful tool to visually display the statistical significance as p-values on Y-axis against metrics like relative risk diff erence, odds ratio, or hazard ratio on X -axis for a given treatment comparison. This paper talks about the interpretation of volcano plot in safety evaluation and construction of graphic elements using SGPLOT procedure statements by providing an example from a late stage clinical trial.

| 186 | What You Need to Know About Submitting Data to the FDA | Pritesh Solanki, Janet Low |
Sponsors need to stay current with FDA requirements and plan to ensure that submitted electronic data are compliant with FDA regulations and review expectations. The focus of this paper is to share lessons learned while preparing clinical tabulations, analysis and site selection packages for Module 5 submission and to address key differences between CBER and CDER. Careful attention must be given to the requirement start dates as these can have significant impact on SDTM and ADaM implementation. FDA guidance continues to change which affects submission throughout the product development lifecycle. Regulatory communication such as waiver requests for data standards and meetings are outlets for sponsors to capitalize on the agreements prior to submission. The lack of data standards awareness may result in delays especially in times where FDA is enforcing technical rejection.
